2 Claims.

Our invention relates to a new and improved machine for printing transfers.

One of the objects of our invention is to provide a new and improved machine for printing transfers with .a fusible ink, so as to produce transfers of the type in which the marking is printed upon a paper base. This paper base is placed against the fabric or other article to be marked, with the transfer impression in direct contact with the fabric or the like, and the transfer marking is released from the paper base by applying a heated iron with suitable pressure.

Another object of our invention is to provide an improved machine'for printing transfers in two colors.

Another object of our invention is to provide a machine for this purpose, said machine including a plurality of printing units, these units being conveniently arranged upon the same level in order to permit the parts to be conveniently inspected and operated, and in order to facilitate making the combined machine ready for twocolor operation.

Another object of our invention is to provide a two-color printing machine which comprises two units arranged and combined so that both units can be simultaneously operated for doing two-,

color work, or both said units can be separately operated on single color jobs, or one of said units 'can be operated on a single color job while the other unit is idle.

Another object of our invention is to provide amachine which comprises a pair of like-printing units, one of said units being mounted upon a base which is adjustable with respect to the frame of the machine, so that the paper can be led in proper registration from one printing unit to the other.

Another object of our invention is to provide an improved machine for two-color printing of the class described, in which the paper web is reversed in an improved manner so that the successive printings shall make impressions upon the same face or surface thereof.

Another object of our invention is toprovide a plurality of printing units for two-color printing of the class described, in which the web of paper is turned 180 in a transverse direction, between the first printing and the second'printing, said web of paper being preferably moved in an inclined downward direction while it is being thus reversed.

Another object of our invention is to provide adjustments and controls for the printing elements of the respective units, in, order to shorten the time for making the machine ready, andin order to control the movement of the web of paper soas to secure proper registration of the suc cessive impressions.

Another object of our invention is to provide a plurality of printing units in which the ink supply means is outwardly directed as this shortens. the time for making the machine ready, and makes it possible to better control the thin web. of paper on which the printing is done.

Other objects of our invention consist of certain adjustments and arrangement of the parts which are set forth in detail in the annexed description and drawings which illustrate a preferred embodiment of our invention, it being un 79 derstood that the above general statement of the objects of our invention is intended to generally explain the same, without limiting it in any manner.

Each printing unit essentially includes a revoluble die and a rubber-covered roller which cooperates therewith.

As shown in Fig. 2, the printing units are respectively designated by the reference letters A and B. As shown in Fig. 1, printing unit or mechanism B is provided with a die D and a rubber-covered roller 19, and the printing unit A is provided with a corresponding die Da, and a rubber-covered roller 19a.

As shown in Fig. 3, each printing die constitutes a revolubly mounted cylinder upon which the design or other identifying mark is formed in intaglio.

As shown in Figs. 1 and 5, the supply of ink la is held upon a doctor blade 63 whose edge is in close contact with the respective die. Each doctor blade 63 is provided with suitable side flanges in order to hold the ink thereon. As each die D is turned, the intaglio design therein takes up ink, and the edge of the doctor blade 63 prevents the smooth surface of the respective die from taking up any ink. Each doctor blade 63 is held in a block 64, which is pivotally connected at 65 to a slidable block 66. The slidable block 66 has a face which makes sliding contact with acorresponding face of a block '72. The block 72 is adjustably connected to the frame of the machine by means of clamping bolts '73. These clamping bolts '73 pass through vertical slots in the'frame of the machine so that the vertical position of the block '72 can be quickly adjusted. Theblock .72 is provided with a horizontal screw 67 having a head which is provided with an operating' handle 68.

- '71 having a perforation through which the screw 69. extends.

The screw 69 passes through an opening in the head of the screw 6'7, and the head of the screw 69 engages a wall of said opening so that the screw 69 cannot be upwardly moved from the position shown in Fig. 5. A nut 70 is provided which can be turned in order to turn the block 64 in the clockwise direction, and thus apply the edge of the doctor blade 63 with suitable pressure against the die D.

As shown in Fig. 3, the die D is provided with conical recesses at its ends, so that the die D is turnably mounted upon pin-point bearings 43 and 43e. The pin-point bearing 43 is provided with an externally threaded portion on which an internally threaded collar 43a is mounted. The collar 43a is provided with a pin 43b which enters a suitable recess in the adjacent end of the die D, so that the pin-point bearing 43 and the die D turn in unison. The pin-point bearing 43 is the end of a shaft 42 which is suitably 55' mounted in the frame of the machine, anti-friction bearings being provided. The shaft 42 is provided with a gear 41 which is connected thereto by means of a suitable set-screwas shown in Fig. 3. A coll 44 is provided on the shaft 42. The n-point bearing 436 is provided at the end of a shaft 42a and this shaft 42a is located within an externally threaded sleeve 45. The externally threaded sleeve 45 is located within an internally threaded sleeve 46 which forms part of the frame of the machine.

The externally threaded sleeve 45 is provided with an integral enlargement 46a having operating handles by means of which it can be turned. A nut 46d is provided for assembling the shaft 42a and its are shown in Figs. 7 and 8. Each end of the shaft 47a is mounted in an anti-friction bearing 47d which is located within a bearing member 516. Each bearing member 516 has a dove-tail recess, and the frame is provided with arms 51d clamped thereto, and these arms 51d are provided with'dove-tail projections .on which the bearing members 51c can vertically slide.

As shown in Fig. '7, clamping screws can be provided for holding the bearing members 51c in adjusted vertical position.

As shown in Fig. 8, each anti-friction bearing 47d is clamped into position by means of an arm 51f which is pivotally connected to the corresponding bearing member 51c, at 519.

The left-hand bearing member 51c which is shown in Fig. 3, is connected by means of a pin 48d to the lower end of a screw 48, which cannot turn about its own axis, but which can be vertically moved up and down by mechanism later described herein. The right-hand bearing member 51c, which is shown in Fig. 3, is connected by meansof a pin 4811 to a box 114 in which the lower end of a screw 48a is located. The screw 480. can turn with respect'to the member 114, but members 114 and 48a move up and down in unison.

As shown in Fig. 3, the member 114 is provided with a clamping screw for locking the screw 48a against turning movement, while permitting members 48a and 114 to move up and down in unison.

As shown in Fig. 10, the vertical screws 48 an 48a pass through internally threaded bushings 110 and 111. These bushings 110 and 111 are located in the interiors of hollow spiral gears 108 and 109. The spiral gears 108 and 109 are in mesh with spiral gears 106 and 107 which are located upon, and which turn with the shaft 48b, which is turned by means of wheel 105. The spiral gears and the shaft 431) are mounted in tiltable bearing members 512) which are shown in Fig. 11. The tiltable bearing members 511) which are pivotally connected to the frame of the machine at 51c, are raised or lowered by means of eccentrics 51a which are mounted upon a shaft 51. The shaft 51 is turned by means of a handle 50. Hence, the rubber-covered roller 19 can be quickly raised or lowered by turning the shaft 51. For example, the rubber-covered roller 19 can be quickly raised in order to insert a web of paper.

A fine adjustment of the verticalposition of the rubber-covered roller 19, with respect to its die D, is secured by turning the shaft 4812. It is clear that when the threaded bushings 110 and 111 are turned, that the screws 48 and 48a are turned so as to raisethe shaft 47a.

In order to secure proper registration of the web of paper, it is desirable to be able to tilt the shaft 47a with respect to the axis of the die D. This is accomplished. by releasing the set-screw provided in the member 114, and then turning the screw 48a by means of the hand-wheel 49.

In order to secure an additional adjustment for securing proper registration of the two impressions on the web of paper, the printing unit A is mounted upon a base 131 which can be laterally adjusted, that is, in a direction perpendicular to the web of paper R.

As shown in Fig. 4, the slidable table or support 131 for the mechanism of the unit A is provided with a downwardly extending projection 130. This is provided with an internally threaded horizontal opening through which a revoluble screw 129 extends. This screw 129 is suitably mounted in a bearing provided in the'frame of themachine.

It is provided with a spiral gear 128 which meshes with gear 127, mounted upon shaft 126 which is provided with a handwheel 125. p

The controls and adjustments before described makes it possible to quickly separate the elements of each printing unit, to adjust the relative vertical position, to tiltone of the elements of each unit with respect to the other, and to laterally adjust the entire mechanism of one unit with respect to the mechanism of the other unit. The fusible ink is maintained in molten condition by means of burners '74, which are supplied with fuel through hollow supports 75. Said supports are suitably connected to a source of gas or other fuel.

Mechanism for driving the apparatus and for guiding the web of paper The roll or web of paper R is spirally wound upon a suitable hollow core or mandrel which can be made of cardboard, and the internal diameter of said core or mandrel is substantially the same as the diameter of the spindle 1. This core or mandrel is held in position by means of disks 5,

which are slidably mounted upon the sleeves 6c. The sleeves 6c are provided with disks 6 which are slidably mounted upon said sleeves 6c. The sleeves 6c are also provided with internally threaded nut members 6a which can be turned upon corresponding threads of the sleeves 60, so

' that the members 5 are moved towards each other in order to clamp the spiral roll of paper in suitable position upon the spindle 1. The sleeves 6c are provided with pawls 3 and 3a pivotally connected thereto, and blade springs 4 and 4a move the pawls 3 and 3a so that they engage the depressions 2 and 2a. The depressions 2 are partial depressions, that is, they do not extend com-- pletely around the spindle 1. This construction makes it possible to laterally adjust the position i of the spiral roll R.

In addition, mechanism is provided for longitudinally and transversely adjusting the position of the spindle 1 in order'to provide a fine ad justment of the position of .the roll R, instead of the relatively coarse adjustment previously ber 11a, so that the screw 11 can turn, but it cannot move in a direction parallel to its own axis. Each screw 11 is provided with an operating handle 12.

Hence, the bearing blocks'9 can be adjusted in a longitudinal direction.

Since the paper is pulled off the spiral roll, it is necessary to interpose a suitable frictional resistance and this is accomplished by means of a brake 15 which is suitably adjusted or tightened by means of a member 16. The brake 15 is provided with an adjusting screw 8 which has a head 10. The adjusting screw 8 passes through an internally threaded opening in the .adjacent bearing block 9 so that the spindle 1 method heretofore employed, for making a plurality of impressions upon the same side of a sheet of paper, as the improvements specified herein lessen the tendency of the web of paper to shift laterally between the first impression and the second impression.

The web of paper, provided with the impressions I, is now led over an idler roller 21a, between the elements 19a and Da of the second printing unit and over the idlers 23 and 2 1, to be wound up in the form of a spiral roll upon. a suitable core or mandrel which is connected to and which turns with the shaft 150. The shaft 150 is mounted in a slidable bearing block 150a which is longitudinally adjustable by means of a screw mechanism of the type heretofore described. The shaft 150 is held in position in its bearing block 150a by means of catches 1501).

As shown in Fig. 1, the shaft 150 is provided with a pulley 151 which is driven by belt 152. The belt 152 is driven by pulley 154 which is mounted on shaft 153. The pulley 15 i is driven by belt 156, which passes around the pulley 157, which is mounted upon the same shaft as a gear 40. Hence, when the gear 40 is turned, the shaft 150 is also turned'in order to wind up the paper which has received the two impressions I. The belt 152 passes around revoluble idlers 151a as shown in Fig. 1.

An electric motor M is suitably mounted upon the frame of the machine and this is provided with a switch box 77 and with the usual starting or speed control box '76 having the usual handle 76a.

As shown in Fig. 1, the shaft of the motor M is provided with a sprocket 25 having a plurality of series of sprocket teeth.

As shown in Fig. 2, the sprocket 25 drives abelt or chain 25a, and this drives a sprocket 26 which is locatedupon the shaft 26a of a speed transmission, which is located in a housing T. The speed transmission which is diagrammatically illustrated is of the well known"Reeves type, and any suitable type of gear transmission may be employed.

The speed transmission is controlled by means of the wheel 160.

The shaft 26a is provided with a speed change pulley 26g which drives a belt 261), which passes over a pulley 26c mounted upon a shaft 26d. The shaft 26d is provided with a sprocket 26f and this drives the chain 26h which drives a sprocket 28. The hub of the sprocket 28 is loosely mounted upon the main shaft 35. In order to connect the sprocket 28 to the main shaft 35,

a clutch sleeve 101 is utilized. This has a projection which enters a recess in the hub of the sprocket 28 and the sleeve 101 can be clamped to the shaft 35 by means of a suitable set-screw. 14o As shown in Fig. 2, the shaft 26a is also provided with a sprocket 26e and this actuates a chain 27 which operates the sprocket 27a, whose hub is also loosely mounted upon the main shaft 35. The hub of the sprocket 2'7a can be con- 145 nected to the main shaft 35, by means of a clutch sleeve 100, which is similar to the clutch sleeve 101. The chain 27 passes over an adjustable idler 34 which can be adjusted in order to regulate the tension upon the chain 27.

7 shown in Fig. 2.

As shown in Fig. .3, the idler roller 34 is located at the end of an arm which is pivotally mounted to the arm 34a, which is suitably fixed to the frame of the machine. An adjusting screw 34b regulates the position of the idler 34 and the tension on the chain 27.

As shown in Fig. 2, the main shaft 35 is provided with alignedshafts 35a and 35b and these aligned shafts 35a and 352) can be connected .to or disconnected from the main shaft 35, by means of clutches C and Ca.

The shafts 35a and 351) are provided with spiral gears 30 which mesh with spiral gears 31, mounted on short transverse shafts on which the gears 40 are also mounted. Each gear 40 meshes with a gear 41 which drives the corresponding die of the printing unit, as shown in Fig. 3. The idlers 18 and 21a may be vertically adjustable. In order to drive units A and Bsimultaneously on a two-color job, the sleeve 100 is moved to the inoperative position shown in Fig. 2, and the sleeve 101 is moved to the operative position The clutches C and Ca connect the shafts 35a and 35b to the main shaft 35.

The joint drive of both units is therefore accomplished by means of sprocket 25, chain 25a, sprocket 26, shaft 26a, belt 26b, shaft 26d, sprocket 26 and chain 26h. r I

In order to drive unit A independently of unit B, the clutch sleeve 100 is moved to the operative position so that the sprocket 27a actuates the shaft 35. The drive of unit A is therefore accomplished by means of belt 27. The clutch Ca is in the connected position, and the clutch sleeve 101 has been moved to the inoperative position.

In order to drive unit B independently of unit A, the clutch sleeve 101 is allowed to remain in the operative position, the clutch sleeve 100 is moved to the inoperative position and the clutch Ca is disconnected.

If it is desired to stop the operation of the machine while it is running, this can be done by throwing out the clutches C and Ca. Likewise, if it is desired to stop the operation of either of the units while the same are running, this,

can be done by disconnecting the respective clutches C or Ca. I

The idler 20 is mounted at the end of an arm 62, which is upon the same shaft as the" gear 61, which meshes with the worm 60 mounted upon the shaft 59. The shaft 59 has a spiral gear 58 which meshes with the spiral gear'57 on the shaft 56, which has the spiral gear 55. lhe spiral gear 55 meshes with the spiral gear 54 which is mounted on the shaft 53a, which is operated by means of wheel 53.

If the unit Bis to be used independently of unit A, the web of paper is led over the idlersl'? and 18, and between the elements of the first printing unit, and it is then led over suitable idlers along the path shown in dotted lines in Fig. 1, so that the paper is wound up on a roller which sewage-- is mounted in a shaft located in the bearing block 1512) slidably mounted on block 1510. If the unit A is to be used independently of unit B, a roll of paper is mounted at the point Rb shown at right-handside of Fig. 1, and the paper is then led over the idler 21, between the elements 19a and Da, and over the idlers 23 and 24 to be wound up at the point Ra.

A supplemental beltdrive 1510 can be used for turning a shaft mounted in the bearing block 1515.

While we prefer to mount both printing units or mechanisms upon a common base or frame, this is not absolutely essential, and we do not wish to be limited to this idea.

Likewise, while we have shown a completely organized machine for performing several different kinds of work, it is clear that we have disclosed various valuable and novel sub-combinations, and we do not wish to be limited to the complete assembly specified. v

The respective printing mechanisms disclosed herein are of identical construction. While we have illustrated a machine for printing transfers, theinvention is not to be limited to a machine utilized for this specific purpose.

We have shown a preferred embodiment of our invention, but it is clear that numerous changes and omissions can be made without departing from its spirit;

We claim:
